At the unix command line if i press Ctrl-C,that does not end a process but rather interrupts it and i return to the shell prompt. So,i have the following two questions:1.Is there a way i can see the list of all interrupted processes and end them ?2.What key combination to press to end a process instead of interrupting it ?

G,H,I
becomes:

View 1 Replies View RelatedA function by name abc is called in many files. I want to copy all the lines with the function call to an output file.A simple grep on function name doesn't help me as the function call is spanning across multiple lines as follows:
abc(parameter1,
parameter2,
parameter3);
So I want to copy all the three lines (till semicolon) to the output file.The problem is because there are more than 200 calls for the same function and I cannot do it manually
one tell me the internal working of kill command. that is how it kills a process internally or from where it picks file to continue its process.

Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.
as we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.
So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.

Is it possible to save the process and log out then log in and continue the process? I know how to pause a process using kill -pause pID and continue it using kill -cont pID. But that only work if you don't log out after pausing it.

View 4 Replies View RelatedMy Foxconn nettop NT-A3500 crashed.
I install Ubuntu 11.04 and enter it. Then I install all available updates(in the update manager), activate AMD/ATI closed source GPU driver(under hardware drivers).
Then I do a reboot(sudo reboot). Then I login and do a VT switch to ex:tty2(CTRL + ALT + F2). Then I input the command "Localhost$ sudo pidof X"
will show the pid I have to kill(kill as root or sudo). Then I kill the pid and the NT-A3500 would crash(usually on first try).
I hope I won't get bashed too much on my first post here. The problem I'm experiencing seems to be well known, yet I haven't come across a definite solution to it while searching the forums. I've got an external drive connected to my laptop via eSATA. When I want to mount it as a normal user from GUI level, I'm required to supply the root password since apparently the system's policy doesn't allow external drives partitions to be mounted.
The closest solution to what I would like to achieve is given by giulix in this post. Yet, with the polkit-gnome-authorization utility removed from Fedora 12 (at least so I've heard on mailing lists), it's difficult to find out where to start in terms of policy editing. What I would like to have is being able to mount this volume as a normal user from GUI level. I know I could just add an entry to /etc/fstab, but it just seems so old-fashioned and tacky, and besides, it's not, um, "dynamic" and wouldn't utilize hal and dbus, so I wouldn't have an icon on the desktop. (it's not really the reason, I'd just like to have things done the way they should be right now).
I started simply to end some processes to see if this would help. Ending dbus-deamon and pushing the shutdown button seems to shutdown the computer and temporarily solve the problem. I see that there are better solutions, so I hope it wont occur again.The problem is, I also ended a lot of other processes, like the clock, trashcan, workpane buttons, the sound button, the WiFi button and the show desktop button (and maybe some more I don't know of. I thought these buttons would automatically reappear after a reboot, but this is not the case. I could add some buttons manually, but I still haven't found the sound button and the WiFi button. Also, when I minimalize a window, it doesn't show anywhere on any panel.Luckily I can use alt-tab
